SPEC IFIGATION forming part of Letters Patent No. 660,718, dated October 30, 1900.

Application filed February 17, 1899- serial No. 705,862. \No model.)

To ctZZ whont it Ill/(by concern:

Be it known that I, EDGAR O. BIsBEE, a citizen of the United States of America, and a resident of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Oil-Oake-Forming Apparatus, of which the following is a specification.

My invention relates'to improvements in oil-cake-forming apparatus, the object being to provide means for molding the product of flax or other oleaginous seed into cakes and extracting the oil therefrom with a minimum amount of labor and expense. The method of forming these cakes as now practiced con sists in first passing the seed through crushing-rolls, after which the meal thus formed is introduced into what is known as a heater or tempering-kettle, where it is steamed or otherwise treated. The meal is then taken from the heater and molded into cakes, which are wrapped by hand in cloths and subjected to pressure in a hydraulic press. I11 following this method a large amount of time is consumed and work involved in wrapping the cakes before and in stripping them after the cakes have been pressed and the oil extracted. My invention is designed to mold the meal into cakes so as to be placed ina press, the oil extracted, and then removed without wrapping the cakes in cloths and in an efi'icient manner requiring a small amount of hand-labor. During the handling of the meal cakes thus formed their temperature is not perceptibly lowered by exposure to the atmosphere, as is generally the case with apparatus now in use, and the output of cakes and oil by the molding and pressing machines is increased with a minimum amount of labor. I accomplish the filling and ejection from the molding-pan and stripping of the cakes automatically. These operations are now performed by hand.

Among the advantages which I claim for my device, as compared with machines now in use, are saving of time and labor and greater uniformity as to weight and shape of the meal cakes.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the molding-machine used with my improved apparatus. Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of the same, parts being broken away to more clearly show the working parts of the device. Fig. 4 is a detail cross-section of a portion of the heater and molding-machine. Fig. 5 is a perspective view of the molding-pan. Fig. 6 is a longitudinal view of the same. Fig. 7 is a detail view of the press, showing one of the improved molding-pans in position for depositing a meal cake on one of its plates; and Fig. 8 is a detail view of the molding-inachine.

In the drawings, let A represent the molding-machine, having framework 2, on which is mounted the heater B for holding and tempering the meal. The lower end of theheater is provided with the plate 3, having an adjustable opening 4, which registers with pocket 5, corresponding in shape to the molding-pan O and formed in the base-plate 6. The base-plate is mounted below the heater upon the framework 2, and opening 4 is provided with sliding shutters 7,which are adapted to be opened and closed by the handle 8 to regulate the amount of meal deposited in the pocket. The shutters project through the heater and are provided with holes corresponding to similar holes in the handle 8, through which a pin is adapted to be inserted, and by swinging the handle the shutter selected is opened or closed, thus increasing or diminishing the size of the opening 4.

The molding-pan 0 consists of a frame for forming the meal into cakes, which is composed of the lower and upper trays l2 and 15. The upper tray is fastened to the lower tray by pins 13, which are free to travel in the inclined slots 14, formed in the sides of the upper tray, so that the trays will expand when the molding-pan is filled and placed in the press: The object of inclining 'the slots 14; is to cause the upper tray to remain in lowered position when the pan is being filled. The end 9 of the pan is open and the opposite end provided with handle 10 and tongue 11. An ejector E is connected so as to slide freely from end to end in the pan by means of the pivoted cams 17 and 18. The screws fastening the cams to the ejector pass loosely through slots 16, the use and construction of the pan to be hereinafter more fully described.

To carry the molding-pan into and out of the pocket for the purpose of filling and packing the meal therein, the reciprocating mechanism D is provided, which is composed of the carrier 19, which travels in the groove 20 of the framework. A carrier-head 21 is fas tened to the carrier by screws 22 and is adapted to engage with the tongue 11 of the molding-pan. The carrier has a reciprocating motion and is operated by means of the rockarm 23, the upper end of which is freely mounted in the slot 24 of the carrier and its lower end journaled to the bearing 25,which is mounted on the framework. A pitman-rod 26 is pivotally connected to said arm and to the crank-wheel 27,which is mounted on shaft 28. The gear-wheel 29 is journaled on shaft 28 and is connected to the friction-clutch 30 and meshes with the pinion 31,which is keyed to the main shaft 32, carrying the drivingpulley 33. The portion 34 of the frictionclutch is attached so as to slide freely on the shaft 28 by means of the feather 35. To throw the clutch into and out of operation, the lever-arm 36 is provided, which is pivotally mounted upon the framework by means of the bearing 37 and connected to the bellcrank 38 by connecting-rod 39. The bellcrank is mounted upon the support 40, which is fastened to the framework and provided with the shifting arm 41, which works in the annular groove 42 of the friction -clutch. The lever passes through the opening 43 of the framework and is positioned so that the cam 18 of the pan C engages, thereby shifting the clutch and disengaging its teeth 45. To throw the clutch into operation, the lever is reversed in movement and thrown to a forward position by hand. To equalize the weight upon the lever, the spring 46 is provided, its upper end being fastened to the lever by the bend or loop 47 and its lower end to the collar 41:8,which is journaled to the framework by bolt.49. The collar 48 is formed with the lip 5l,with which the screw 50 comes in contact, so as to adjust the tension of the spring.

WVhen it is desired to mold a cake, the pan 0 is placed in the passageway 52,with its tongue 11 in engagement with the carrierhead 21 and its cams 17 and 18 hanging in the longitudinal grooves 53 and 54 of the framework and the lever 36 thrown forward. In Fig. 1 the molding-pan and parts of the mechanism are shown when the pan has been passed part way into the pocket 3. The upp er end of the lever 36 is forward and the clutch in position so as to connect with the operating-shaft, which is kept continually revolving by the pulley 33 and operating-belt. (Not shown.) The carrier thus reciprocates and when the pan 0 is being filled with the pomace carries the moldingpan into the pocket until its open end comes in contact withthe wall 55, having the slanting lug 56, which projects into the end of the pan, thus causing the end of the cake of meal when formed to be smooth and free from ragged edges. The opening 5 in the pocket leading from the heater maybe varied in size by opening the shutters 7, so that the carrier and molding-pan will make one, two, or more complete strokes or passes before the ejector E will be pressed to the inner end of the pan and the cam 18 in position so as to operate the lever and clutch, thereby switching reciprocating mechanism D out of and the shifting mechanism G into operation, which is for the purpose of disengaging the pan from the carrier and shiftingit from the passage-way.

The shifting mechanism G consists as follows: A cross-head 57 is loosely recessed into the framework A and mounted upon the connecting-bar 58. This bar is mounted in the groove 59 of the framework and held by cleats 60, so as to slide freely in the groove. Its end is fastened to the upper end of the rock-arm 61 by pin 62, which is adapted to work in the slot 63; The lower end of the rock-arm 61 is pivotally fastened to the framework, and between its ends is journaled the pitman-rod 64:, which is operatively connected to the crankwheel 65 by journaling. This crank-wheel is journaled to the framework A by bolt 66 and is operatively attached to the rod 67, which is mounted upon the framework by passing the bolts 68 through the slotted openings 69.

The rod 67 is provided with notch 70, which is adapted to engage the pin 71 when the shifting mechanism is in operation. This pin is mounted upon the end of the crank-arm 72, which connects to the crank-wheel 73, mounted upon shaft 74. This shaft is journaled upon the framework and connects, by means of the gear 75 and pinion 76, with the operating-shaft 32, thereby continually operating when the machine is in motion, causing the pin and the connecting-rod 67 to oscillate backward and forward, thereby transmitting motion to the shifting head 57 when the lever-arm is operated and the reciprocating mechanism thrown out of operation.

The rod 67 is provided with the pin 77, which as the rod passes forward engages withthe lug 78, mounted on the block-arm 79. This block-arm is mounted upon the frameAand provided with guide-slots 80, through which,

the bolts 81 pass. The block-arm 79 is provided with a spring-dog 82, which is fastened to the bar by bolt 83 and formed with shoulder 84, the lower end of which projects and is free to work vertically in the opening 85. This shoulder is adapted to engage the outer end-of the switch-bar 86 when the lever-arm 36 is forward, as shown in Fig. 1, and the block-arm 79 moved forward. The switchbar, composed of spring material, is pivotally connected to the framework A. It passes below the lever-arm 36 and is provided with the rib 87, which is adapted to engage the notch 88, so that the switch-bar and the lever-arm operate. simultaneously when either one is shifted.

The trip-bar 67 is provided with the dog 89, which is adapted to spring or raise the switch-bar when the lever-arm 36 is in normal position, so that the shoulder 84 will pass freely when the block-arm 79 is sliding forward. The spring-dog is provided with the adjusting device 90, by which the height of the shoulder can be adjusted. The blockarm 79 is also provided with the bevel-shoulder91, which is positioned and carried by the block-arm so as to block the entrance of the notch and to raise the pin 71 from enga'gement therewith when the pitman-rod 72 has completed its stroke. It is evident that when the pan has been carried backward and forward and filled, so that the cam 18 trips the hand-lever, the bar 79 is operated, and the pin 71 simultaneously drops into the notch 70 when the pitman completes its stroke, whereupon the shifting mechanism operates. As the shifting head slides forward the molding-pan is deposited upon the table of the machine and cleared from the passageway leading to the pocket, and the machine is then in readiness for a new pan. The completion of the stroke of the ejector finds the bar 86 resting upon the dog 82, as shown in Fig. 8, and the entrance of the notch 70 in the bar 67 blocked, as shown in Fig. 1. After the lever is thrown forward, so as to fill the new pan, the operator passes the filled pan to the press F, hereinafter more fully described. As the pan passes into and out of the pocket 5 the meal in the heater B follows into the pocket through the opening 5. The valves are adapted to regulate the amou ut of meal thus deposited and can be opened and closed so as to fill the pan during one, two, or more strokes of the carrier. The heater B is of ordinary construction and provided \vith the cylinder 92, in the center of which is vertically erected the shaft 93, having journal-bearing upon the bar 94. The stirring-arms are mounted upon the lower end of the shaft and are adapted to constantly agitate the meal over the opening 5, so as to keep the meal from packing, and when the pan is withdrawn to refill the pocket. The pocket is provided with the outlet-opening 96 and a valve 97. handle 98 the meal in the heater can be emptied out.

The press F, of ordinary construction, is composed of the framework 99, ramrod 100, ram-head 101, plates 102, links 103, and guideposts 104. Each of the plates may be provided with cloths, which are endless in form to pass around rollers mounted upon each of the plates for convenience in stripping from the cakes. As shown, each end of each plate is provided with rollers and 106, which are respectively journaled to bearing-arms 107 and 108. The rollers 105 are provided with tension-springs 109, which are mounted in slots 110, formed in the bearing-arms 107, which are fastened to the plates by means of screws 111, which pass through the slots into the plates. The bearing-arms 108 are fas- By opening the valve by means of tened to the plates by means of screws 112. It is thus seen the roller-cloths stretch around each of the plates over the rollers and are free to revolve. The pans are adapted to be passed over the cloth and plates to the position as shown in Fig. 7, and the notches 113 are adapted to engage the lugs 114:, which are formed on the trays and positioned on either side of the roller-cloths 115, so as to guide the pans when being placed on the trays. When a pan is thus positioned, the handle 10 is grasped by the hand and the pan drawn from the press. The first movement throws the edges 116 of the cams into engagement with the pins 117, which are fastened to and cause the upper sections 15 of the pan to rise, thus loosening the cake contained therein. The ejector E remains stationary relative to the plates, but slides in the pan and causes the cake to be deposited upon the roller-cloth, whereupon the pan is lifted from the plate and is again ready for refilling. After the cakes have been deposited on the plates the press is operated by the ram, asis ordinarily done, and

the oil extracted from the meal, after which the ram is released and the cakes removed from the plate. The cloths loosen from the top faces of the cakes contained in the press as the plates are lowered and the ram returned to its normal position, as shown in Fig. 7. When the cakes are removed from the press, the cloths on the lower faces of the cakes follow and strip as they pass around their respective rolls 105, assuming the cakes to be removed from the end at which they were passed into the press.

It is obvious the device is operative without cloths or cloths without rollers.

An operative pan may be constructed open on top. A machine for filling such a pan may be of various constructions, equivalents being substituted for minor portions of the machine herein indicated without departing from the principles applied by me in my invention.
